WARP-DYEING MACHINE.

T 0 all whom it may concern:

Be it known that I, WALTER F. HAsKELL, a citizen of the United States,residing at lVestbrook, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in VVarp- Dyeingl\/Iacl1ines, 0f which, the following is a specification.

My invention relates to machines for dyeing warps and other likematerial and it relates particularly to an improved construction of amachine or apparatus shown in my Letters Patent No. 1,029,866 dated June18, 1912.

In the machine described in said patent, as illustrating the invention,I make use of a coil of pipes vertically disposed and connected byhollow heads in which are located guide rolls. 1

The heads and pipes were so arranged that the warp would pass throughthe coil extending down through one pipe up through the next in orderand so on, passing over the several rolls which were journalled in thehollow heads.

The object of the invention was to con-- fine the dye in narrow channelsso that it than round as was necessary to useonly a relatively smallquantity and to convey back'to the point Where the dye was supplied tothe coil the partially spent dye as it arrived at a point where the warpleft the machine.

In my present invention, while I have made use of the same generalprinciples, I have devised a much simpler construction than that whichwas illustrated inmy prior patent.

'While my invention was not limited in this'respect, I soon found thatthe crosssection of the pipes would be better oblong the warp strandwhich was made up of a large number of individual threads tended toflatten out so that it would -in'tl1e patent was also expensive to build7 that the machine could be Serial No. 478,213.

The above considerations led me to im- Specification of Letters Patent.Patented Jain, 10, 1922, Application filed October 11, 1918, Serial No.257,687. Renewed June 16,1921.

Inthe improved form of my machine, I

simplicity and cheapness of construcmake use of a tank which ispreferably long and narrow in plan with considerable vertical height.

The interior of the tanktis divided by.ver-. tical partitions extendingfrom side to side of the tank and dividing the interior into a series ofelongated passages alternately connecting at the upper and lower ends.so that a continuous passage for the warp will be formed between thepartitions. The guide rolls for the warp are journalled at the pointsabove and below the par-' titions where the passagescome together andare designed to hold the warp in the central portion of ,each passage.

In the accompanying drawing, I have illustrated a warp dyeing machinebuilt according to my present invention in which Fig. 1 is a centrallongitudinal section, Fig. 2 is a plan view and Fig. 3 a section similarto Fig. l of'a small portion of the tank showing enlarged partitions forthe purpose of narrowing the cross-section of the passages.

tank of considerable height and relatively narrow in proportion to itslength. The tank is divided into a series of passages by means of aseries of cross partitions 2 and 3 spaced apart uniformly. Each of thepar; titions 2 extends from the bottom of the tank. to a point somewhatbelow the top, and each of the partitions 3 extend from; the top to apoint a short distance above the. bottom of the tank.v

There is thus formed in the tank a con tinuous duct or passage extendingfrom end to end, the several passages connecting at, their upper andlower ends.

. Kportion of-the guide rolls 4-are journalled at the top'of'thefl tankand as here shownthey extend' entirely across from one .side to theother.

The lower guide rolls 5 are journalled at a short distance above thebottom ofthe tank andthe rolls each connect the adjacent passages.

The warp strand 13 composed of many individual warps, or the strand madeup of sag piece goods or any other material dyed in this machine, passesdown through the end passage, thence over the rolls and through theseveral'passages in succession and out at the other end of the machine,all the dye used being confined in this continuous pas- A feeding basin6 is shown as being provided at the endof the tank where the fresh dyeis supplied to the machine and a suitable duct .7 connects the upperportion of thelast passage 8 with the first passage 9.

. through or piece goods or other fabric which may make a wide fiatstrand may be used.

The cross-section of the connecting passages may be regulated by thethickness of the artition and in Fig. 3, I show a small section of atank wherein the partitions 12 are considerably expanded andthe passagesconsequently narrowed up.

It is evident that the smaller the crosssection of the passages the lesswill be the amount of dye required to operate the machine. I c

' Guide rolls 10 are provided for guiding the warp to the machine, andsqueezing rolls 11 are located at the outlet of the machine to squeezeout the surplus dye.

' Apparatus for washing and otherwise treating the dye, notnecessary toshow in this application, may be used after or before the dye passesthrough this machine.

- The machine may be used as a single dye-' 1. In a machinefor dyeingwarps or other like material, the combination of a tank having a seriesof transverse partitions arranged to' form a continuous passage for dyeliquor through the tank, guide rolls journalled' in line with saidpartitions for retaining the warpv strand in said passage and means forsupplying liquor to the inlet of said passage.

2. In a machine for dyeing warp or other like materials, the combinationof a tank having a series of transverse partitions, the alternatepartitions extending from the top down to a point above the bottom andfrom the bottom to a point belowthe top to form a continuous passagethrough the tank,

. guide rolls journalled in line with said partitions for guiding thewarp through said passage and a duct for conveying the spent liquor fromthe outlet to the inlet end of said tank.

In a machine for dyeing warp or other like materials, the combinationof a tank having a series of transverse partitions .arranged to form 'acontinuous passage through the tank, and guide rolls journalled in linewith said partitions for retaining. the Warp strand in said passage anda duct for conveying the spent liquor from the outlet to the inlet endof said tank.

In testimony whereof I aflix my signature.
